Common questions in Naperville.
Why does Naperville have its own electric utility, and how does that affect HVAC rebates?
Inside Naperville city limits, electricity is provided by the City of Naperville Electric Utility rather than ComEd, while Nicor Gas supplies natural gas. That means Naperville homeowners primarily utilize Nicor Gas efficiency rebates for furnace and thermostat upgrades, while neighboring suburbs like Lisle, Wheaton, and Plainfield can access both ComEd and Nicor Gas programs.
Should I replace my whole-home humidifier when I replace my furnace in Naperville?
Usually, yes. Most Naperville homes have a furnace-mounted humidifier that suffers from hard-water mineral scale after 10 to 15 years. Installing a fresh humidifier when the sheet-metal plenum is already being rebuilt is fast and cost-effective.
Does the City of Naperville require a permit and inspection for furnace and AC replacements?
Yes. The City of Naperville Transportation, Engineering & Development (TED) department requires a permit and post-installation inspection for HVAC replacements. Our licensed partner crews handle permitting and inspection coordination.
Naperville climate and homes.
Naperville climate and homes.
Naperville sits inland from Lake Michigan, so summers run hotter and winter nights colder than on the lakefront. Many large two-story homes run zoned or twin systems.
Your local weather
Located inland from Lake Michigan in IECC Climate Zone 5A, Naperville misses the lake's moderating influence—meaning summer afternoons regularly run 5 to 8 degrees hotter than the Chicago lakefront, and clear winter nights drop deeper below zero.
Homes and ductwork
Naperville's housing stock is dominated by 2,500-to-4,500+ sq. ft. two-story colonials and traditional homes over full basements. Many run a single large basement system with motorized zone dampers—or twin basement/attic systems—alongside whole-home bypass humidifiers and 4-to-5-inch media air cleaners.
Utilities and rebates
City of Naperville Electric Utility (municipal electric within Naperville city limits) or ComEd (in surrounding DuPage/Will County suburbs), and Nicor Gas for natural gas. Nicor Gas offers residential rebates for qualifying 95%–97%+ AFUE furnaces and smart thermostats.
